I changed my fuel filters last night and left the water separator valve open. I drove truck this morning down the road and it died on me. I stopped and fuel was pouring out of the valve. I closed the valve and the truck would not start again. I am not sure if understand how to purge the system correctly because i don't ahve a manual, but i have tried to turn key on for 30 seconds and then shut off and continuing to do this. I ran the batteries down so i am charging them again. I turned key on and pushed a key into that schrader valve that is close to the upper filter. I a couple of air bubbles came out, but it still wont' crank. it cranked once or twice earlier in the day and wouldn't stay running.

Should i try to get it to run on a small amount of starter fluid ....it turns over, but won't crank. Is it possible that an air bubble is keeping fuel from leaving the upper filter and entering the engine. I am at a complete loss here.

i did it like twenty times. How long do you shut the key off for and where does the air exit the system at.

you should just have to turn the key to the off position. The air is forced through the system by the fuel being pumped into the engine and will eventually be forced out. Turn key to on position without trying to start. Leave it there for 30 secs. turn key off. Repeat at least 6 times for normal fuel filter replacement. I'm assuming you cracked the top filter and cycled the key until it was recieving fuel. Tighten and keep cycling the key for 30 secs. It should eventually start but will probably take a while to purge all the air since you airbound the whole system.

I don't think i am getting an fuel pumping in order to get the air out of the system. I have tried to bleed the high and low pressure out of the system and there is no fuel coming out. So I am open for suggestions.
